(RNN) - Severe weather and tornadoes slammed parts of the Midwest and South on Sunday, killing at least one in Oklahoma and 13 in Arkansas.

Arkansas Department of Emergency Management confirmed that seven died in Faulkner County, five died in Pulaski County and one died in White County, all counties to the north of Little Rock.

The same storm headed northeast to Vilonia, AR, where the fire chief called it a "mass casualty situation."

Vilonia is no stranger to deadly tornadoes. One struck the town on April 25, 2011, killing four.

Bad weather through the night complicated the search for casualties. Search and rescue teams were told by the National Weather Service in Little Rock, AR, to watch out for gusty winds.

"It's been a truly awful night for many families, neighborhoods and communities, but Arkansans always step up to help each other recover," Arkansas Gov. Mike Beebe said via his Twitter account.

One was killed and a fire station was destroyed in Quapaw, OK, on Sunday afternoon, according to The Associated Press. Quapaw is located in the northeast corner of Oklahoma.

A storm chasing team's vehicle was damaged in Mayflower after they say they "got a little too close."

"We were picked up spun around all glass broke bleeding. But alive," the storm team wrote on Facebook.

Interstate 40 in Arkansas was closed for a time Sunday night as authorities removed debris from the roadway, the Arkansas State Patrol reported, but one lane in each direction has been reopened for essential traffic only.

Severe weather wextended across Nebraska, Kansas, Oklahoma, Missouri and Arkansas throughout Sunday afternoon and evening, according to the National Weather Service.

At least 25 were injured by a tornado in Baxter Springs, KS, that destroyed about 100 homes and businesses. Baxter Springs, KS, is six miles north of Quapaw, OK. One person died in Baxter Springs, but it wasn't immediately clear if the death was storm-related, the Associated Press reported.

Massive storm destruction was also reported in Odessa, MO, and Plattsburg, KS, KCTV in Kansas City reported.

In association with the strong line of storms moving through the state overnight, flooding was reported in northeast Arkansas, between Imboden and Pocahontas, and in Maynard, according to KAIT.

Authorities in Bollinger County, MO, were attempting to rescue a 70-year-old man from high water, KFVS 12 in Cape Girardeau, MO, reported.

At least 10,000 customers of the Electric Cooperatives of Arkansas were without power Sunday night.

Storm watches and warnings continued into the early morning Monday, with a large swath of the nation's midsection affected, including flash flood warnings for several counties in north Arkansas and southeast Missouri.

The restrictions would include prohibitions on watering lawns so much that the water flows into the street, using a hose to wash down sidewalks, or using a hose without an automatic shut-off nozzle to wash cars.
